Bug ID: 81822
Summary: [RX] Should implement __atomic_compare_exchange
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: olegendo at gcc dot gnu.org
Target Milestone: ---
Target: rx*-*-*
There are some places which check if the target directly supports SImode atomic
compare and exchange, via the __GCC_ATOMIC_INT_LOCK_FREE macro. In particular
the C++ std library.
The atomic pattern should be implemented to improve library and user code
compatibility.
